Even if the gauge is wrong, as long as it is consistent, it gives you something to base the pressure on. I use a 0-30 pound air pressure gauge.
If I remember correctly, my 200 would pump right at 27 pounds at 6200 rpm. If your gauge shows 25 pounds, just watch for any drop in pressure. If you go along for months reading 25 pounds then it suddenly drops 2-3 pounds, time for a look. Could be a worn impeller, could be a scratched housing. On you boat, I would not run for long if it drops to 10 pounds or less. I would rather be safe than buying a new block.
